LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 545,797, datedSeptember 3, 1895.

Application filed May 3, 1895. Serial No. 548,001. (No'modeld To allwhom it may concern.-

Be it known that 1, WILLIAM P. Ilnnsznv, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Locomotives, of which the following is a specification.

The object of my invention is to so construct a locomotive of thepassenger type having large driving-wheels that a long, wide, and deepfire-box may be used. In constructing the ordinary passenger-locomotivethe depth of the fire-box has been sacrificed when width and length wereobtained, and when depth was obtained the fire-box was very muchcontracted. By my invention I am enabled to increase the length andwidth of the fire-box and at the same time obtain the depth required.

In the accompanying drawings, Figure 1 is a side view of the locomotiveconstructed in accordance with my invention, the wheels being shown bydotted lines. Other details of the locomotive have been omitted in orderto more clearly illustrate my invention. Fig. 2 is a longitudinalsectional View illustrating the fire-box. Fig. 3 is a transversesectional view on the line 3 3, Fig. 2.

A is the frame of the locomotive.

B B are the driving-wheels.

Z) Z) are the front truck-wheels, and Z) are the trailing wheels.

The wheels B B are mounted on axles B, journaled in suitable boxes 0,adapted to the frame A, and the trailer-wheels b are mounted on axles Bjournaled in boxes 0, adapted to the frame.

D is the boiler of the ordinary construction, D is the fire-box, and Dis the cylinder-castin g. The boiler has a seriesof tubes d, adapted tothe tube-sheet 01', (shown in Fig. 2,) and below the grate d is theash-pit D The frame A is depressed at d in front of the fire-box, sothat while the portion A is of one level and will readily accommodatethe axles of the large driving-wheels the portion A is on a lower leveland will readily accommodate the axle of the trailer and will extendunder the fire-box to the rear of the locomotive, so as to be coupled tothe tender. It will be understood that the frames of all forms oflocomotives usually extend to the rear, so that the pulling strain willbe taken by the frames direct and not through other parts of the 10-oomotive. The frames have generally extended directly on the line of theportion A, and thus the depth or width of the fire-box was sacrificed toaccomplish the object.

In the drawings the lower portion of the fire-box rests directly abovedepressed portions A of the frame A A, as shown in Fig. 3, and bydepressing the frames at the points a, I obtain the increaseddepth offire-box and at the same time keep the width required, and as the frameis depressed I can extend the fire-box to the rear, increasing itslength without interfering in any way with other parts of thelocomotive. Consequently I can construct a locomotive that will have anincreased grate area and a uniformly deep firebox that will give resultsnot obtainable in other locomotives.

I claim as my invention- 1. The combination in a locomotive of the sideframes depressed back of the drivers, the driving wheels and trailers,the boiler, the fire box, the sides of which are directly above thedepressed portion of the frame and within the space between theoppositely arranged driving wheels and the trailing wheels so that awide and uniformly deep fire box is obtained which extends forwardbetween the driving wheels, substantiallyas described.

2. The combination of the frames A, A of a locomotive, depressed at adirectly in front of the fire box, the boiler and the fire box ofuniform depth, the side walls of the fire box being directly above thedepressed portion of the side frames and within the space between theoppositely arranged driving wheels and trailers and having an ash pitextending between the frames and grate bars separating the ash pit fromthe fire box, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
